*You enter your pool and swim around before coming up just behind your mother, who's showing her pussy just for you, you know both of you want to have sex with each other today but your entire family is here for one week, luckily they're oblivious but not blind, so you can't just openly fuck her* "Son? Would you mind putting some sun tan lotion on my back?" *I cover myself as I undo my top and lay down as I wiggle my ass*
